Specification of Letters Patent. Patentd ltalgll, 1919:.. mi Applicationed April-21, 1916. Serial No.'92,"66. I l

invention is `more clearly understood from the following specification,the subject mat- -ter of the claims, and =the views illustrated in theaccompanying drawings, in which:

Figure l 1s a `vertical sectional vlewv through the device, showing thedetail con# struction thereof.

Fig. l is a perspective view `showing the shown Fig. 5 is a' view inlelevation of one of the '4 T-bolts used in connection with the yoke ofFig-4 for attaching the device to2-an engine.

Referring to the drawings wherein similar reference characters denotecorespond` ing parts throughout theY several views, 1 denotes the upperportionof the cylinders of an engine, 2 the exhaustv manifold, and.

3 the exhaust pipe leading centrally therey from.

The exhaust manifold 2 consists prefer ably yof yan elongated cylinderprovided with rounded ends and its exhaust pipe 3 extending from itslower side at a point midway between its ends and disposed obliquelytherefrom for a portion of its distance. At onefside of the exhaustmani` fold 2 are formed the ported exhaust nipples el.' adapted to-beseated in the ends of-` the exhaust ports of the engine.

TWithin the exhaust manifold 2 is the in-v` take manifold 5 provided atone of its sides k with the intake nipples 6 which. project* through theside of the exhaust manifold?` and are adapted to be seated within thein;

take ports of the engine. f` The intake mani:-A

fold` 5 is also preferably formed of an elongated cylindricalconstruction provided with rounded ends, and 4is of less length and lessdiameter than the" exhaust manifold 2 to provide ample spacetherebetween, and extending from the under side ofthe intake manifold5.' and from a point substantially midway between its ends is' theintake pipe y7 whichl is also disposed in oblique'direction {'ffrom theintake manifold 5 for a portion of :fits distance-and within and inspaced relaj vtion to vtheexhaust pipe 3,Ithe lower portion of th-intakepipe 7 being curved later- `ally in 'acute 'angular relation toprovidethe attaching end 8 W'hich project'sthrough and ,i'beyond one 'of theside ,walls `of the exhaust 'p1pe.3.':Within the end 8 ofthe intake pipeattaching end l8 of the intake pipe'7 is any Lsuitable form of kerosenecarbureter 1l) supwith oilvbythe pipe 11. Secured to thecarbureter l()is the Vhot air pipe 12, provided with the .butterfly-valve 13 operated'byfany suitable means. The hot air pipe;

reter 10. As shown,`.'the open end of the hotair cas- 2 5 .ing1svdisposed innermost and adjacent the juncture of the exhaust' p-ipe l3with the exhaust 'manifold so vthat the heat radiated 1 from them andthe surrounding warm air.

t ,'may'be drawn directly into the hot air casing and again superheatedin its passage along "beneath the exhaust manifold just prior toitsfentrance into the kerosene ear- ,buret'en y .Y

The intake manifold ,5 and its intake pipe "7 are supported -in ,spacedrelation to and '.Within'the exhaust vmanifold 2 and its exhaust pipe A3tlnough the medium of the -intake nipples/6 which ,project from one side"of the intake'manifold 5 and open through one 'side wall of the exhaustmanifold 2. The nipples 6 thus connect the intake manifold5. with theexhaust manifold 2, and at the oppositesside o f the intake manifold 5vthere is a lletgor neck which connects -adjacent wall`of the exhaustmanifold 2. Also extendingfrom the outer Wall of the intakepipe 7 at anysuitable point is another llet or yneck'similar to the fillet or,

.neckj15 for securing this side of the intake pipe 7 tothe adjacent wallof the exhaust pipe 3.- l The intake manifold 5 and its intake pipe 7are also additionally reinforced 4 and supported by the Vattaching end 8of the ntake pipe 7 being rigid with and opening through one of thewalls of the exhaust pipe .i s'th'ebuttery valve 9 operated through'aiiysuitable means. 2,Suitablysecured to the this wall of thiintakemanifold -5 with the screw threaded in the outer end ofl the neck 15isthe tube 17 ofthe valve casing 18 provided With any suitable form' ofvalve 19 actuated by the valve stem 2O which extends .t0 the dash boardof the automobile or other4 70 suitable point7 and connected to thevalve casing 18 is the water pipe or hose 21 leadirg from' any suitablesource of water supp .Y- i

F or supplying gasolene to the intake pipe 7 of the intake manifold5`the lower fillet tends to the dash board of the automobile or otherconvenient point', and for supplying 85 gasolene to the valve casing 23the pipe or hose 25 is provided which leads to any suitable source ofvgasolene supply.

For securing the device upon an engine the yokes or U-shaped bolts v26provided 90 with'the threaded ends 27 and the nuts 28 thereon areemployed. These yokes 26 extend around and embrace substantially half ofthe circumference of the exhaust manifold 2 and have their threaded ends27 se- 95 cured in the apertures 29 formed in the ends ofthe heads 30upon the stems 31 of the T- bolts, the stems 31 of these bolts beingdesigned to pass through bores formed between the cylinders of theengine and secured 101 thereon by the nuts 32 which engage thethreadedends 33 of the T-shaped bolts at the oppositeside of the engine.This means of attaching the device upon the engine firmly Vsecures thesame thereon with the exhaust nipples 4 of the exhaust manifold 2securely seated in the ends of the exhaust ports of the engine and theintake nipples 6 firmly seated in the ends of the inlet ports oftheengine, which connections may be efliciently sealed with any suitableform of gaskets or the like, the attaching end 8 of the intake pipe 7being connected to the 'kerosene carbureter 10 in any suitable manner asat 34 and the exhaust pipe 3 having 115 its end 35 connected in anysuitable manner with the exhaust conducting pipe.

The operation of the device is briefly described as follows:

To mart the engine the valve stem 24 is manipulated for actuating thevalve in the valve casing 23 so that the gasolene will be drawn throughthe pipe 25 and into the intake pipe 7 and therethrough into the vintakemanifold 5 and into the respective cylinders of the engine bythesuction' created therein and air may be admitted to the gasolene fromthe air pipe 12 by the proper manipulation of the butterliy valves 9 and13 if desired.. The engine will now run 130 by the gasoline suppliedthereto until the exhaust manifold 2 and its pipe 3 and the intakemanifold 5 and its intake pipe 7 become heated by the exhaust gases ofthe engine whereupon the kerosene carbureter -10 will be so operatedthat the kerosene will the port 16 in the upper neck 15 inra fine streamand by the heat of the exhaust gases which'have heated the surroundingwalls of the exhaust manifold 2, the intake manifold 5 and the fillet orneck 15 is readily 'converted into steam and commingles with thevaporized kerosene and gasolene, the gasolene, however, being graduallycut olf by manipulating the valve stem 24 inthe opposite direction untilthe gasolene is entirely cut olf and the engine now runs eiiicientlyuponthe kerosene mixture, the kerosene having been thoroughly vaporized bythe air heated in the casing 14 which passes through the hot air pipe 12into the carbureter 10, the steam increasing the efficiency of themixture. v

Having described my invention, what I claim as new and desire to secureby Letters Patent, is l 1. In an internal combustionv en 'ne, the

- combination with an exhaust mani oldhaving` a depending exhaust' pipeupon its lower side and middle portion, of an intake pipe, a part ofwhich is `wholly within said exhaust pipe, while the remaining part ofsaid intake pipe has on its receiving end a lateral extension fitted tothe under side of the exhaust manifold and provided with a receivingopening immediately adjacent the exhaust pipe of said manifold, wherebyinitially heated air from the exhaust pipe will enter said intake.

2. In an internal combustion engine, the combination with an exhaustmanifold having a discharge pipe and also having an intake manifoldpositioned within the exhaust manifold, of an integral hollow neckconnecting said manifolds, a liquid supply pipel connected to the outerendof said neck, and a valve to regulate the supply of liquid to saidneck.

3. The combination with an exhaust manifold operatively connected to theexhaust ports of the engine and having a depending exhaust pipe on itslower central portion, of .an intake pipe operatively connected with theintake ports of the engine and disposed vpartly within said exhaust pipeand manifold, said intake pipe having its exterior portion or receivingend shaped to fit the under side of the exhaust manifold and extendedinwardly to apoint adjacent the point of union of said exhaust pipe withsaid exhaust manifold, whereby the only opening in the intake pipe willbe immediately against said exhaust pipe.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.A
